Undersea Discovery - Aquarium Exhibit in Tucson

Undersea Discovery at Flandrau in Tucson

Undersea Discovery

Submerged in Science!

Our newest exhibit is teeming with interesting and colorful creatures, hands-on activities, and an intertidal touch experience where you can interact with ocean inhabitants under staff guidance.

From its intertidal zone where visitors get to handle living coral reef residents to the midnight zone where guests can investigate creatures of the deep, Undersea Discovery represents an exciting new way for our community to learn about ocean science, conservation, and marine biology.

Things to See and Do

  • Intertidal Touch Experience - See, touch, and learn about intertidal life under the guidance of Flandrau staff. See times and information below.
  • Coral, Kelp Forest, and Open Ocean Tanks - Discover the different plants and animals who live in these unique regions of the sea.
  • Giant Squid (sculpture) - See eye to huge eye with this 25-foot-long adolescent giant squid sculpture and learn about these mysterious creatures in the Midnight Zone. Here, visitors learn about the special adaptations creatures like vampire squids and angler fish need to live under immense pressure.

Intertidal Touch Experience

A Flandrau staff member waits to greet visitors at the aquatic touch tank

In this experience, a trained Flandrau staff member will introduce you to various animals that live in the Earth's intertidal zones.

Demonstration time runs for 30 minutes in total.

  • Weekdays at 3:00PM
  • Weekends at 11:30AM, 1:30PM, and 3:00PM

Visitors will be taught how to safely hold some of our ocean guests briefly while there. The invertebrates you will meet (or animals without backbones) may be wiggly but they are excited to meet you! Please listen carefully to directions from the Flandrau team member assisting you.
